Easter Egg

After opening the door with the loader you need to keep going until you come to the dark area with all the Facehuggers. Kill the Facehuggers and when moving on look out for a blue glowing switch. Activate the switch and go back into the room where you came from. A door now opened up. Go into the room and you should see 4 Alien Eggs on the ground. The trophy / achievement will pop as soon as you enter the room.
